North Korea Launches Missile and Tries To Jam GPS Signals (go.com)
An anonymous reader writes: Hours after North Korea fired a short-range missile into the sea in retaliation for ongoing U.S. join military drills with South Korea, they started jamming GPS navigation systems near its border with South Korea, affecting hundreds of fishing boats but not causing any immediate danger. There were no disruptions to drivers' satellite navigation system or air traffic, but warning messages were broadcast in affected areas warning ships not to rely on their GPS navigation. In a statement, the South Korean Ministry of National Defense said: "North Korea has been continuously disrupting GPS system since 7:30 pm [Thursday] and thereby interfering and hampering our military movements, which is threatening the safety of our people."
The little dog that used to just go yap yap yap is now frothing at the mouth, too. Isn't it time to euthenize it?
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
Mostly it's a sign that we have South Korea's back and neither will be intimidated by North Korea's antics. If anything, North Korea is stirring things up by continuing to launch missiles, conducting nuclear tests, and making threats. I find it hard to look at this and see how either South Korea, Japan, or the US could be considered provocative in this situation. The US stirs up plenty of trouble elsewhere, but we're not doing that here. If anything, we've tried to cooperate more with China on appropriate sanctions, which is a step in the right direction.
It's whiplash's way of trolling people who complain that every article about a new product is a paid advertisement. It's a joke for April Fool's Day.
AFAICS North Korea is best interpreted as a toddler who is indulging in tantrums to get attention. If that's the case, we have a problem. The normal toddler can be safely ignored while it goes on and on. However such a brat is not capable of doing any real damage. Whilst we may wish to assume that the NK leadership isn't suicidal, that's a hard call given just how nutty they seem to be. However it may be the best solution - just ignore them at a real level, although letting their latest threats get into the media so they don't feel totally ignored and so raise the stakes. But it could be worse - they could believe they will be rewarded in an afterlife for being destructive...
There's really no such thing as "jam proof" - merely resistant. Even directional antennas are not perfectly directional, and will still receive off-axis signals, just at some attenuated strength. Any sufficiently strong nearby source can overwhelm a much more distant and weaker source.
In a "real" war, it wouldn't be jamming that is the problem anyway. The problem would be that the GPS constellation would go bye-bye from the other guy's anti-sat weapons. Not that many countries have those, but the most sophisticated adversaries do have them.
The US actually likes to provoke NK. If NK gets riled up, it gives the US more excuses to place more troops or missile defenses in S. Korea/Japan. These missile defenses would do nothing to help S. Korea, considering that N. Korea has tons of artillery already pointed towards Seoul which is only a few miles from the border. Instead they only use is to help contain both Russia + China. More so towards containing China.
The thing is that the north Korean people need to solve this
And that has worked out so well for the people in Syria, Egypt, and Libya.
How come Slashdot never gets Slashdotted?
Probably a technology test. Jamming GPS in a conflict would inconvenience the south and their allies a lot more than the north, so it's understandable they'd want the capability.
I wonder what is there to be gained by provoking them with militarily exercises?
Eat a little too much propaganda for breakfast?
The purpose of military training exercises is not to "provoke" somebody, that is childish and silly.
The purpose is to practice fighting in the conditions that a war might take place in. In case it happens.
If we wanted to "provoke" them, we would just fire artillery across the border, and watch them be provoked.

Unless you're doing it in front of their house.

We gathered valuable information about North Koreas ability to jam GPS and some experience doing operations under those conditions. So, seems like a net gain for the US to me.
any idea how much energy is required just to reach the GPS system?
ON TOP OF WHICH, you have to go ballistic to 12,540 miles, in 6 staggered orbits 60 degrees apart, and take out a significant number of the 32 birds to the point where it is impossible to get a lock on four at once. Which means taking down 60% of them.
Easier just to jam it. 1575MHz gear can be had over the counter.
